Tonight's update crashing IE11

32-bit versions of Internet Explorer were crashing after Intrusion Prevention System (IPS) 20150220.001 definition package was applied to their Norton Products. We have released a fix for this issue through our LiveUpdate servers. See the Security Response Blog Article for more information.

Running NIS on Windows 7 Pro 64-bit with IE11 (latest updated). Sometime this evening, IE11 started crashing. In fact, it crashed an already-open browsing session, and now trying to start it up just instantly causes a "Internet Explorer Has Stopped Working" error.

Tried resetting IE11 settings to default. No change. Tried running IE11 in no-addons mode. No change. The error is shown as the following:

Now, IPSEng32.dll is a Norton file. So I uninstalled NIS. Bingo - IE11 started working like normal. Re-downloaded and re-installed NIS. At the outset (said last updated 20 hours ago) IE11 worked fine. Then it auto-updated and applied a patch... and instantly IE11 stopped working again. Ergo, something Norton did is breaking my IE11. Doesn't seem to have affected another computer I have running IE10.

Any ideas?

EDIT: The other IE10 PC had been asleep and hadn't updated NIS yet. It is also now crashing in exactly the same manner as this one... and since that PC is almost entirely unrelated to this one in terms of software being used, this is going to be a bigger problem than just me.

Re: Tonight's update crashing IE11

Not sure what that thread is trying to point out... but I don't have competing software running.

I have a third PC that's barely used for anything, also running W7 Pro / IE10... started it up, IE was fine, forced Norton to update (said last updated 6 hours ago)... bam. IE10 stopped working. This is not a coincidence.

Re: Tonight's update crashing IE11

Thanks, if that was the intention, then yes - none of these systems are running anything beyond NIS. The final system I mentioned breaking is as bare bones as it can get, so I can't imagine any conflict on it with other system software or add-ons.

One of the issues with getting this problem reported is unless the person has multiple browsers or devices to use, there's no easy way to diagnose or even report the issue. It's not even clear from the way IE crashes that the problem is even vaguely related NIS - you have to dig into crash reports to find the faulting module.

Not to sound dense... but where in NIS do I have the security history log? The interface is redesigned literally every year, and I have no idea where that is...

Re: Tonight's update crashing IE11

Same issue here, actually was using IE when the updated started and them BOOM everything came crashing down. Glad to know that Symantec with all of the reductions and cuts to staff still has time to properly test their code. Note the sarcasm. One would think that this would be an easy Q&A check.

Re: Tonight's update crashing IE11

I have the same problem. Was running fine today. Then Norton updated and crashed IE11 that had been working fine up to that point. I have uninstalled NIS and IE started working. Then reinstalled NIS, and once the patch was deployed IE started crashing again.

Re: Tonight's update crashing IE11

I completely remopved Norton 360 from my machine, rebooted, and reinstalled. It was wroking okay until the patch ran, then it crashed IE 10 on my Windows 7 64 Bit Machine.
Definitely the path that did it. I checked all during the updates, and IE was running fine until the patch and reboot.

Re: Tonight's update crashing IE11

Okay... looking at the logs on a system I didn't remove NIS from... I think this might be a bad definition update. I see reference to Intrusion Prevention Engine 7.1.1.18 and driver 4.2.1.9 from earlier this afternoon when everything was fine, but on the one system that auto-updated... the only thing shown as updating at the moment that things stopped working, was a change to:

Stop with all the rhetoric and fix this. Can't get on the blink'n Internet all of a sudden and find this is going on! Now forced to work off of Chrome, which was the only way I could get on this forum by the way. Worked fine until about 2 hours ago when apparently a patch was installed by you guys. This is not the way to keep customers. Safari is beckoning even sooner than I planned

Re: Tonight's update crashing IE11

I had to restore to 11/19. IE 11 worked for a few minutes until the live update ran. Once it ran then I lost IE. Right now I had to use the restore point to 11/19 again. I have the live update turned off just to type this. The problem is in the update.

What rhetoric? I am a user just like you and I have reported it. Do you want me to click my fingers and have this fixed? ... Can't happen!!!

Re: Tonight's update crashing IE11

Honestly, though... if someone's going to push an untested update at 8:30 PM PST on a Friday night, then they should hang around long enough to make sure they don't have to un-push it. I can't imagine the fallout if every Norton user is stuck without internet access on a weekend!

(Don't forget that not everyone has multiple browsers installed, and if they don't, there's no way to even get another one without intuitively knowing to uninstall Norton.)
